SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 277,652, dated May 15,1883. Application filed April 7, 1883, (No model.)

To all whom it may concern Be it known that we, JAMES AINSLIE and ROBERTAINsLIn, citizens of the United States, residing at Brooklyn, in thecounty of-Kings and State of New York, have invented new and usefulImprovements in Spring Bed-Bottoms, of which the followingis aspecification.

This invention relates to that class of spring bed-bottoms in which twoframes composed of metal bands or slats are connected together by spiralsprings and the bed-bottom hinged at the middle, so that it can befolded for transportation.

- The object ofourimprovement is to strengthen the structure and toarrange and construct the parts so as to provide a convenient anddesirable spring bed-bottom.

To such end our invention consists in a spring bed bottom having itsends and side slats connected together by metallic cornerpieces, withits side rails made in sections, which are hinged together at one ormore points by butt-hinges or suitable pivot-connections, and itssprings connected to the top and bottom slats of the two frames by meansof their bent ends entering perforations in the slats, said membersbeing connected and organized substantially as hereinafter described,and pointed out in the claim.

Figure 1 represents a top view of the spring bed-bottom. Fig. 2is a sideview of the same. Fig. 3 illustrates one of the corner-pieces detached.

A A indicate the two frames of the spring bed-bottom. Each one of theseframes con sists of the long outer side slats, B, the outer end slats,G, the cross slats D, and the longitudinal slats E, which can beinterlaced, if desired. The longitudinal slats are riveted at their endsto the end slats, and the cross-slats are fastened at their ends, in asimilar manner, to the side rails. The end and side rails meet at theirterminals, and are riveted together to constitute the corners of theframes. As the fastenings at the corners of the frames are liable tobecome loose, we provide for each corner of the frames an angular metalstrengthening-plate, F, which is riveted or otherwise fastened to themeeting ends of the end and side slats, thus holding said slats securelytogether and strengthening the structure. The frames are connected bymeans of the spiral springs G, which have their ends carried over thecross-slats and then bent inwardly at right angles and inserted inperforations formed in said slats. fastening, and admits of the springsbeing readily applied. The spring bed-bottom thus formed is divided atthe middle and its two halves or sections hinged together, so that thebed-bottom can be folded for transportation. This is effected bydividing each frame into two parts and connecting the side andintermediate longitudinal slats by means of butt-hinges H, which, whenthe springs are disconnected, admit of the frames being folded.

By the above it will be seen that the bedbottom is strong andreversible, readily put to gether, and exceedingly simple in itsstructure.

We have herein shown the bedbottom di vided into two parts or halves byforming each outer side rail of each longitudinal rail of two sections;but it will be evident that they could' he made in more than twosections, and hence butthinges employed at more than one point.

Having thus described our invention, what we claim is- A springbed-bottom as a structure, having its ends and side slats connectedtogether by metallic corner-pieces, with its side rails made in sectionshinged together at one or more points by butt-hinges, and its springsconnected to the slats of the two frames by means of their bent endsentering perforations in the slats, said members being connected andorganized substantially as described.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
